Market evolution: Saturated polyesters excluding PET (CN 39079980) — 2015–2025

Introduction

This report analyzes the trade dynamics of the European Union for CN code 39079980—a category of saturated polyesters in primary forms, excluding common types like polycarbonates, alkyd resins, and PET. The analysis covers the period from 2017 to 2025, for which consistent annual data is available. Despite being a residual category encompassing various specialized polyesters, the product line shows significant and evolving trade patterns. The EU has maintained a persistent positive trade balance in this sector, though its magnitude has fluctuated. Over the period, the market has been characterized by rising prices, shifting trade partnerships, and increasing export orientation, punctuated by significant supply shocks in recent years.

1. A Resilient Surplus Under Price and Volume Pressures

The EU’s overall trade performance for saturated polyesters reveals a complex picture: while the value of both exports and imports has grown, the underlying volumes have followed divergent paths, indicating substantial price inflation.

The Enduring Trade Surplus Amid Value Growth

The EU has consistently exported more of these polyesters than it has imported in value terms, recording a trade surplus throughout the period. The surplus started at €225.6 million in 2017 and stood at €224.0 million in 2025. While the percentage change over this period was a marginal -0.7%, the path was not linear. The surplus peaked at €251.1 million in 2021 before contracting sharply in 2022, driven by a surge in import values. This indicates that while the EU remains a net exporter, its competitive edge was temporarily challenged.

The Dominant Role of Price Increases

The most striking feature is the divergence between value and volume trends. Export volumes fell by 8.1% while their value grew by 9.3%, implying a significant increase in the average export price. Import prices saw an even steeper rise. This broad-based price inflation (€/t) is a primary driver of the nominal value growth observed in the trade balance.

2. Geographic Reorientation and Shifting Concentrations

The EU's trade partners for these polyesters have undergone a significant reconfiguration, with China emerging as the dominant import source and traditional partners showing varied performance.

China's Ascendancy in EU Imports

The most dramatic shift has been the surge in imports from China. In 2017, China was the fourth-largest source of EU imports by value (€86.1 M). By 2025, it had become the undisputed leader, with imports valued at €184.8 M—a 114.7% increase. Conversely, imports from the United States, while remaining the second-largest source, decreased by 8.8%. Imports from Taiwan saw a substantial decline of 31.3%, dropping from €87.2 M to €59.9 M. This reorientation increased the concentration of EU import sources; the Herfindahl-Hirschman Index (HHI) for imports by value rose from 1,468 in 2017 to 1,494 in 2025, indicating slightly higher supplier concentration.

Divergent Trends Among EU Export Markets

EU export flows show more volatility. The most notable change is the collapse of exports to the Russian Federation, which fell by 77.3% from €85.3 M in 2017 to just €19.3 M in 2025, likely reflecting the impact of geopolitical tensions and sanctions. Meanwhile, exports to the United Kingdom (the largest market) grew by 20.9%, and exports to Mexico surged by 57.3%, becoming a significant growth market. The overall export market concentration (HHI) decreased slightly from 876 to 843, suggesting a modest diversification of destination markets despite the loss of Russia.

Specialisation and Internal EU Dynamics

Within the EU, Germany is the clear leader, accounting for nearly 30% of production value and about 30% of extra-EU exports in 2025. Italy is also highly specialized and a major producer/exporter. The most specialised member state in 2025, according to the Revealed Symmetric Comparative Advantage (RSCA) index, was Luxembourg, though its absolute trade volumes are small. On the import side, Germany, Belgium, and the Netherlands were the largest entry points in 2025. Production within the EU grew healthily over the period, with quantity rising 19.9% and value increasing 31.5% between 2017 and 2025, suggesting robust domestic capacity alongside trade growth.

3. Heightened Volatility and the 2022 Supply Shock

The period was not marked by linear trends; it experienced significant volatility, culminating in pronounced supply and price shocks, particularly in 2022.

Elevated Volatility, Especially in Imports

Trade volatility, measured by the coefficient of variation (CV) of annual values, was generally higher for imports than exports. The most volatile import partners were Saudi Arabia (CV 1.11) and Thailand (CV 0.56), indicating highly unstable supply. Among top partners, China’s import flows were also relatively volatile (CV 0.31). On the export side, flows to Russia became the most volatile (CV 0.37), a direct consequence of recent disruptions.

The 2022 Shock: Geopolitics and Price Spikes

The year 2022 stands out as a period of acute disruption. Three major price shock events were detected in export flows that year:

1. Exports to Mexico: An abnormal price increase of 27.6%.
2. Exports to the Russian Federation: An abnormal price surge of 62.3%.
3. Exports to India: An abnormal price increase of 56.2%.

These shocks align with the broader context of the energy crisis and the initial phase of the conflict in Ukraine, which likely caused raw material cost inflation and logistics dislocations. The shock to Russian exports is particularly notable given the subsequent collapse in volume, suggesting a period of severe market disruption and price volatility before the trade relationship deteriorated.

Resilience Reflected in Autonomy Metrics

Despite these shocks and growing import reliance from specific partners like China, the EU’s overall structural position remained strong. The Net Import Reliance (a measure of dependence on foreign supply) stayed negative throughout, ending at -7.9% in 2025, confirming the EU is a net exporter. More impressively, the Export Propensity (exports as a share of domestic production) more than doubled, rising from 25.3% in 2017 to 53.6% in 2025. This signals that EU industry has become significantly more export-oriented and integrated into global markets for these polyesters.

Conclusion

Over the 2017-2025 period, the EU market for saturated polyesters (CN 39079980) demonstrated resilience and significant transformation. The Union successfully maintained its status as a net exporter, underpinned by a strong and increasingly export-oriented domestic production base. However, this performance occurred against a backdrop of substantial structural shifts and external shocks.

Key dynamics included a dramatic reorientation of imports towards China, which has become the EU's dominant supplier, and the near-complete loss of the Russian export market due to geopolitical strife. The period was characterized by pervasive price inflation that boosted nominal trade values despite softer volumes. This culminated in the volatile year of 2022, which saw extreme price shocks in key export markets, reflecting the broader macroeconomic and logistical crises of that time. Ultimately, the data portrays an EU industry that is globally competitive and expanding its export reach, but one that must navigate an increasingly complex and volatile international trade environment with shifting supplier landscapes and recurring supply-side disruptions.
